It is hard to see the gender of the kittens when they are this small, but now I think that there is only one boy, white or lilac, and three girls – one white, and two dark ones – seal or blue or chocolate. But we cannot be certain either about gender or color until they are about three weeks old.
In a few days they will start opening their eyes. For now they are just getting rounder. 🙂
Siamese kittens are born white. They may look all white and pink to you on the pictures, but you probably notice that some of them have started getting dark ear edges and nose tips. They will fully develop their point color as they get older.
The pointed Siamese pattern is a result of the partial albinism gene. The point restricted pattern is bound to an enzyme which, when exposed to temperatures above 37°C, causes the hair root to produce little or no pigment for the growing hair. That is why the Siamese kittens are born completely white – it is very warm in mom’s belly!
The neck and the body of the cat are warmer and don’t develop any or little pigment at adult Siamese. Their point color is restricted to the areas of the body that are cooler, such as the face, ears, legs, and tail. But, if your Siamese is a bit overweight, a layer of fat works as an insulator and the cat can become darker in its body also!
